Description

Gegenstand der vorliegenden Erfindung ist ein Verfahren zum Entfernen von gebrauchten elastomeren Bezügen von Walzen sowie eine Vorrichtung zur Durchführung dieses Verfahrens.The present invention relates to a method for removing used elastomeric covers from rollers and an apparatus for performing this method.

Gebrauchte elastomere Bezüge von Walzen sind bisher entfernt worden entweder durch Abbrennen oder durch Abdrehen. Das Abbrennen ist verbunden mit Schadstoffemissionen. Wegen der beim Abbrennen entstehenden Wärmeentwicklung ist es nötig, die Kerne anzubohren und zu verstiften. Dabei kann es trotzdem zu Überhitzungen und damit zu einem Verzug der Kerne kommen. Auch können gelegentlich die Zapfen ausglühen. Die nach dem Abbrennen verbleibenden Altgummischläuche sind nur sehr kostenaufwendig entsorgbar. Insgesamt erfordert das Abbrennen relativ hohe Mengen an Energie.Used elastomeric covers of rolls have been removed either by burning off or by twisting. Burning is associated with pollutant emissions. Because of the heat generated during the burning process, it is necessary to drill and pin the cores. Nevertheless, overheating and therefore a distortion of the cores can occur. Occasionally, the cones can burn out. The waste rubber hoses that remain after burning are very expensive to dispose of. Overall, the burning process requires relatively large amounts of energy.

Beim Abdrehen gebrauchter elastomerer Bezüge von Walzen entstehen Fließspäne, die nur schwierig zu entsorgen sind. Die langen Fließspäne erhöhen erfahrungsgemäß das Unfallrisiko. Bei der Entfernung von gebrauchten elastomeren Bezügen durch Abdrehen ist weiterhin nicht zu vermeiden, daß gegen Ende stets auch die oberste Schicht des Kerns abgetragen wird. Dieses Verfahren ist somit stets mit einem gewissen Durchmesserverschleiß verbunden.When twisting off used elastomeric covers from rollers, chips are created that are difficult to dispose of. Experience has shown that the long flowing chips increase the risk of accidents. When removing used elastomeric covers by twisting off, it is still unavoidable that the top layer of the core is always removed towards the end. This process is therefore always associated with a certain diameter wear.

Die DE-OS 22 48 853 beschreibt ein Arbeitsverfahren zur Vorbereitung von abgefahrenen Kraftfahrzeugreifen zur Runderneuerung, bei dem der Restgummi vom Reifen mit einem rotierenden Messer abgeschnitzelt wird, wobei die Schneide des Messers vorzugsweise gerillt ist. Die Rillen in der Schneide sind vorzugsweise konisch eingeschliffen. Diese Messer werden vorzugsweise in einem Fräskopf eingesetzt. Es entsteht dabei eine schuppenartige Oberfläche, welche mit dem zur Erneuerung aufgebrachten Rohmaterial eine besonders innige Bindung eingeht.DE-OS 22 48 853 describes a working method for preparing worn motor vehicle tires for retreading, in which the residual rubber is shredded from the tire with a rotating knife, the cutting edge of the knife preferably being grooved. The grooves in the cutting edge are preferably ground in conically. These knives are preferably used in a milling head. This creates a scale-like surface, which forms a particularly intimate bond with the raw material applied for renewal.

Die US-PS 2,265,643 beschreibt ein Schneidewerkzeug zum Abraspeln der Oberfläche von Gummireifen, die runderneuert werden sollen. Mit diesem Werkzeug soll eine glatte Oberfläche geschaffen werden, auf der dann die Runderneuerung stattfindet.US Pat. No. 2,265,643 describes a cutting tool for rasping off the surface of rubber tires which are to be retreaded. This tool is intended to create a smooth surface on which the retreading will then take place.

Die US-PS 1,971,428 beschreibt ein Werkzeug, mit welchem überschüssiges Gummi von geschwollenen Druckrollen entfernt werden soll. Auch hiermit werden nur relativ dünne Schichten vom Gummibelag entfernt, um wieder eine glatte Oberfläche zu schaffen.US Pat. No. 1,971,428 describes a tool with which excess rubber is to be removed from swollen pressure rollers. Again, only relatively thin layers are removed from the rubber covering in order to create a smooth surface again.

Die US-PS 1,718,793 beschreibt eine Vorrichtung, mit der Gummiflächen aufgerauht werden sollen, die anschließend miteinander verklebt werden sollen, um den inneren Schlauch von Autoreifen zu bilden. Dem gleichen Zweck dienen Verfahren und Vorrichtung zur Herstellung eines Schlauches gemäß DE-OS 14 79 623. Es wird eine dünne Schicht entfernt, um eine rauhere Oberfläche zu erhalten.The US-PS 1,718,793 describes a device with which rubber surfaces are to be roughened, which are then to be glued together to form the inner tube of car tires. The method and device for producing a hose according to DE-OS 14 79 623 serve the same purpose. A thin layer is removed in order to obtain a rougher surface.

Die US-PS 2,398,763 beschreibt eine Schneidevorrichtung für weichen Gummi, Baumwolle und Filz mit loser Textur oder faseriger Zusammensetzung. Diese rotierende Schneidemaschine weist eine besondere Gestaltung der Schneidezähne auf. Figuren 6 und 7 zeigen die Herstellung einer länglichen Kerbe oder die Entfernung der äußeren Schicht einer Walze auf einen geringeren Durchmesser. Geschnitten wird mit Hilfe eines sehr speziell und kompliziert geschliffenen Sägeblattes, welches rasch stumpf wird und nur mit großem Aufwand wieder nachgeschliffen werden kann. Dieses Gerät ist nicht geeignet, die relativ harten aber elastischen Elastomerschichten von gebrauchten Walzen zu entfernen. In der Praxis wurden daher die gebrauchten Elastomerbezüge von Walzen entweder durch Abbrennen oder durch Abdrehen entfernt.U.S. Patent 2,398,763 describes a soft rubber, cotton and felt cutter having a loose texture or fibrous composition. This rotating cutting machine has a special design of the incisors. Figures 6 and 7 show the making of an elongated notch or the removal of the outer layer of a roller to a smaller diameter. Cutting is carried out with the help of a very special and complicated ground saw blade, which quickly becomes blunt and can only be reground with great effort. This device is not suitable to remove the relatively hard but elastic elastomer layers from used rollers. In practice, the used elastomer covers were removed from the rollers either by burning them off or by twisting them off.

Sowohl das Abdrehen wie das Abbrennen ist zeitlich aufwendig und deshalb mit relativ hohen Kosten verbunden.Both turning off and burning off are time-consuming and therefore involve relatively high costs.

Die Erfindung hat sich die Aufgabe gestellt, das Verfahren zum Entfernen von gebrauchten elastomeren Bezügen von Walzen dahingehend zu verbessern, daß es wirtschaftlicher, sicherer, umweltfreundlicher und letztendlich einfacher und schneller durchführbar wird.The object of the invention is to improve the process for removing used elastomeric covers from rollers in such a way that it becomes more economical, safer, more environmentally friendly and ultimately easier and quicker to carry out.

Diese Aufgabe wurde jetzt gelöst dadurch, daß an ein Ende des Bezuges der rotierenden Walzen bis dicht an den Walzenkern ein rotierender Messerkopf herangeführt wird, der mehrere an einem Wendeplattenhalter montierte Schneidwerkzeuge aufweist und dieser Messerkopf an der rotierenden Walze entlanggeführt wird bis zum anderen Ende des Bezuges, wobei Umfangsgeschwindigkeiten der Schneidwerkzeuge von 15 bis 70 m/s, vorzugsweise 40 bis 50 m/s zum Einsatz kommen.This object has now been achieved in that a rotating cutter head is brought up to one end of the cover of the rotating rollers, close to the roller core, which has a plurality of cutting tools mounted on an indexable insert holder and this cutter head is guided along the rotating roller to the other end of the cover , peripheral speeds of the cutting tools of 15 to 70 m / s, preferably 40 to 50 m / s being used.

Sofern es sich um Elastomere handelt mit einer Shore A Härte von mehr als 90, werden die Schneidwerkzeuge mit Drehstählen ausgerüstet. Sofern es sich um Elastomere mit einer Shore A Härte bis ca. 90 handelt, haben sich Ringstähle hervorragend bewährt. Bei beiden Verfahrensvarianten entstehen anstelle von Spänen kleine Teile mit annähernd gleicher Größe. Bei Verwendung von Drehstählen entstehen Chip-ähnliche Teilchen. Bei den erfindungsgemäß eingesetzten hohen Schnittgeschwindigkeiten verhalten sich die gebrauchten elastomeren Bezüge nicht mehr wie Elastomere, sondern wie gut schneidbare Materialien wie Holz oder Kunststoffe. Diese Verhaltensweise war bisher nur beobachtet und angewendet worden bei der Oberflächenbearbeitung von Elastomeren gemäß EP-A1-0 625 406.If it is elastomers with a Shore A hardness of more than 90, the cutting tools are equipped with turning tools. In the case of elastomers with a Shore A hardness of up to approx. 90, ring steels have proven themselves extremely well. In both process variants, small parts with approximately the same size are created instead of chips. Chip-like particles are created when using rotary steels. At the high cutting speeds used according to the invention, the used elastomeric covers no longer behave like elastomers, but rather like easily cut materials such as wood or plastics. This behavior had previously only been observed and used in the surface treatment of elastomers according to EP-A1-0 625 406.

Bei diesem Verfahren werden aber nur sehr dünne Schichten der Oberfläche entfernt. Es war nicht vorherzusehen, daß mit entsprechend höherer Energiezufuhr und entsprechend anderen Werkzeugen wie Ringstählen oder Drehstählen in einem Arbeitsgang der gesamte gebrauchte elastomere Bezug von Walzen entfernt werden kann, wobei es nicht einmal zur Beschädigung oder Verschleißerscheinungen des Walzenkernes kommt.With this method, however, only very thin layers of the surface are removed. It could not have been foreseen that with a correspondingly higher energy supply and corresponding other tools such as ring steels or turning steels, the entire used elastomeric covering of rolls could be removed in one work step, with no damage or signs of wear to the roll core.

Um einen Durchmesserverschleiß am Kern mit Sicherheit zu vermeiden und die Lebensdauer der Schneidwerkzeuge am rotierenden Messerkopf zu verlängern, wird dieser nur bis dicht an den Walzenkern herangeführt. Es verbleibt somit eine dünne restliche Schicht der gebrauchten elastomeren Bezüge auf dem Walzenkern. Dieser wird vorzugsweise entfernt mit einer oder mehreren nebeneinanderliegenden rotierenden Scheibenrundbürsten mit gezopften Stahldrähten. Diese Scheibenrundbürste wird dabei nach hinten versetzt aber gleichzeitig mit dem rotierenden Messerkopf an der rotierenden Walze entlanggeführt. Dabei wird der verbliebene Rest der elastomeren Bezüge in Form von Staub entfernt. Der Walzenkern wird dabei jedoch nicht beschädigt oder wie beim Abdrehen teilweise abgetragen.In order to reliably avoid diameter wear on the core and to extend the service life of the cutting tools on the rotating cutter head, it is only brought close to the roller core. This leaves a thin remaining layer of the used elastomeric covers on the roll core. This is preferably removed with one or more rotating disc brushes with braided steel wires lying next to each other. This round disc brush is moved backwards but at the same time is guided along the rotating roller with the rotating cutter head. The remainder of the elastomeric coverings are removed in the form of dust. However, the roller core is not damaged or partially removed as when turning.

Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß die aus den elastomeren Bezügen durch Schneiden entstehenden Teilchen und der durch das Nachbürsten entstehende Staub abgesaugt werden können. Es handelt sich dabei um leicht zu lagernde, zu transportierende und zu entsorgende Teilchen, die gegebenenfalls sogar einer Wiederverwendung als Altgummimehl zugeführt werden können.Another advantage of the method according to the invention is that the particles resulting from the elastomeric covers by cutting and the dust generated by the post-brushing can be extracted. The particles are easy to store, transport and dispose of and can even be reused as waste rubber.

Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß der rotierende Messerkopf nach Beendigung der Bearbeitung einer Walze die Bearbeitung der nächsten Walze in entgegengesetzter Richtung vornehmen kann. Es ist somit nicht nötig, den rotierenden Messerkopf und die rotierende Scheibenrundbürste in die Ausgangspositionen zurückzufahren.Another advantage of the method according to the invention is that the rotating cutter head can carry out the processing of the next roller in the opposite direction after the processing of one roller has ended. It is therefore not necessary to move the rotating cutter head and the rotating disc round brush back to the starting positions.

Es ist vielmehr nur nötig, die Position der rotierenden Scheibenrundbürste gegenüber dem rotierenden Messerkopf zu versetzen, so daß bei der Bearbeitung der nächsten Walze in der entgegengesetzten Richtung wiederum die rotierende Scheibenrundbürste nach hinten versetzt aber gleichzeitig mit dem rotierenden Messerkopf an der nächsten rotierenden Walze entlanggeführt werden kann.Rather, it is only necessary to shift the position of the rotating disc round brush relative to the rotating cutter head, so that when the next roller is machined in the opposite direction, the rotating disc round brush is in turn displaced backwards but at the same time it is guided along with the rotating cutter head along the next rotating roller can.

Die Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens besteht aus

  • a) einer Werkzeugmaschine zum Einspannen und Rotieren der Walzen mit einem Support zum Vorschub und Anstellen des Schneidwerkzeugs
  • b) einem rotierenden Messerkopf mit einem Wendeplattenhalter und einem eigenen Antrieb für den Messerkopf.
The device for carrying out the method according to the invention consists of
  • a) a machine tool for clamping and rotating the rollers with a support for feeding and adjusting the cutting tool
  • b) a rotating cutter head with an insert holder and its own drive for the cutter head.

Der Wendeplattenhalter wird je nach Härte des gebrauchten elastomeren Bezuges entweder mit Drehstählen oder mit Ringstählen ausgerüstet. Da die überwiegende Anzahl der Walzen mit elastomeren Bezügen ausgestattet sind bis ca. 90 Shore A, werden überwiegend Ringstähle eingesetzt. Da die meisten elastomeren Bezüge nur Stärken bis zu 25 mm aufweisen, kann erfindungsgemäß mit Ringstählen gearbeitet werden mit einem Durchmesser von 50 mm. Mit diesen Ringstählen können Bezugstärken bis zu 25 mm in einem Arbeitsgang entfernt werden. Der rotierende Messerkopf erzeugt dabei Umfangsgeschwindigkeiten von 15 bis 70, vorzugsweise 40 bis 50 m/s. Bei diesen hohen Schnittgeschwindigkeiten verhalten sich die gebrauchten elastomeren Bezüge wie nicht elastomere, aber gut schneidbare Materialien wie z.B. Holz und gut schneidbare Kunststoffe. Bei elastomeren Bezügen mit über ca. 90 Shore A sind die Ringstähle nicht mehr einsetzbar, so daß man übliche Drehstähle anwenden muß. Wendeplattenhalter sind prinzipiell so ausrüstbar, daß die Drehstähle in beiden Arbeitsrichtungen eingesetzt werden können. Es ist somit auch bei dieser Verfahrensweise möglich, eine Walze auf dem Hinweg und die nächste Walze auf dem Rückweg zu bearbeiten.Depending on the hardness of the elastomeric cover used, the insert holder is equipped with either turning steel or ring steel. Since the majority of the rollers are equipped with elastomeric covers up to approx. 90 Shore A, ring steels are predominantly used. Since most elastomeric covers only have a thickness of up to 25 mm, ring steels with a diameter of 50 mm can be used according to the invention. With these ring steels, reference thicknesses of up to 25 mm can be removed in one operation. The rotating cutter head produces peripheral speeds of 15 to 70, preferably 40 to 50 m / s. At these high cutting speeds, the used elastomeric covers behave like non-elastomeric, but easily cut materials such as wood and easily cut plastics. The ring steels can no longer be used for elastomeric covers with more than 90 Shore A, so that conventional turning steels must be used. In principle, insert holders can be equipped so that the turning tools can be used in both directions. It is therefore also with this procedure possible to machine one roller on the way out and the next roller on the way back.

Übliche Wendeplattenhalter besitzen mindestens zwei, meist aber mehr Schneiden. Vorzugsweise wird erfindungsgemäß mit Wendeplattenhaltern gearbeitet, die vier Schneidwerkzeuge aufnehmen können.Usual insert holders have at least two, but usually more, cutting edges. According to the invention, preference is given to working with indexable insert holders which can accommodate four cutting tools.

Zur Entfernung der auf dem Walzenkern verbliebenen Reste der elastomeren Bezüge wird dieser vorzugsweise mit einer oder mehreren nebeneinanderliegenden rotierenden Rundbürsten mit gezopften Stahldrähten entfernt. Dazu weist die erfindungsgemäße Vorrichtung zusätzlich auf

  • c) einen weiteren Support zum Vorschub und zum Anstellen einer rotierenden Scheibenrundbürste mit einem eigenen Antrieb.
To remove the remnants of the elastomeric covers remaining on the roll core, the latter is preferably removed with one or more rotating round brushes with braided steel wires lying next to one another. For this purpose, the device according to the invention additionally has
  • c) further support for feeding and for turning a rotating disc round brush with its own drive.

Auch diese Bürsten werden vorzugsweise so ausgestaltet, daß sie mit Umfangsgeschwindigkeiten von 15 bis 70, vorzugsweise 40 bis 50 m/s arbeiten. Handelsübliche Scheibenrundbürsten sind nicht breit genug, mit gleicher Arbeitsgeschwindigkeit wie der rotierende Messerkopf den Rest der verbleibenden elastomeren Bezüge vom Walzenkern zu entfernen. Vorzugsweise werden daher mehrere derartiger Bürsten nebeneinander montiert, so daß eine Wirkbreite von 1 bis 2 cm entsteht.These brushes are also preferably designed so that they work at peripheral speeds of 15 to 70, preferably 40 to 50 m / s. Commercial round disc brushes are not wide enough to remove the rest of the remaining elastomeric covers from the roller core at the same working speed as the rotating cutter head. Preferably, therefore, several such brushes are mounted side by side, so that an effective width of 1 to 2 cm is created.

Weiterhin wurde festgestellt, daß die Wirksamkeit und die Lebensdauer der Scheibenrundbürsten deutlich verbessert werden können, wenn die Zöpfe der Stahldrähte mit einem elastischen Kunststoff verklebt sind. Besonders bewährt haben sich hierfür Polyurethane, Heißschmelzkleber und thermoplastische Blockcopolymere. Diese Verklebung mit einem elastischen Kunststoff erhöht einerseits die Steifigkeit der gezopften Stahldrähte und erhöht somit die Aggressivität der Bürste. Andererseits verbleibt dem Zopf eine gewisse Restelastizität, so daß der Walzenkern nicht durch die Stahlbürste beschädigt wird, wie dies durch zu kurze und zu starre Stahldrähte der Fall sein könnte. Diese mit einem elastischen Kunststoff verklebten Zöpfe der Stahldrähte und daraus hergestellten Scheibenrundbürsten sind Gegenstand des deutschen Gebrauchsmusters 296 08 399.2.Furthermore, it was found that the effectiveness and the service life of the round disc brushes can be significantly improved if the braids of the steel wires are glued to an elastic plastic. Polyurethanes, hot-melt adhesives and thermoplastic block copolymers have proven particularly useful. This gluing with an elastic plastic increases the stiffness of the braided steel wires and thus increases the aggressiveness of the brush. On the other hand, the braid has a certain residual elasticity, so that the roller core is not damaged by the steel brush, as could be the case with steel wires that are too short and too rigid. These braids of the steel wires glued with an elastic plastic and disc brushes made from them are the subject of the German utility model 296 08 399.2.
